Operational Amplifiers

What are Operational Amplifiers (OP-AMP)?

Operational Amplifiers belong to the differential amplifier family. The other members of the differential family include the fully differential amplifier, the instrumentation amplifier, the isolation amplifier and the negative feedback amplifier. The Op-Amp functions as a electronic voltage amplifier that produces over a thousand times the voltage that comes through one of its inputs.


What Makes for an Ideal Operational Amplifier?

  • Infinite open-loop gain
  • Infinite voltage range available at the output
  • Infinite bandwidth
  • Infinite input impedance
  • Zero input current
  • Zero input offset voltage
  • Infinite slew rate
  • Zero output impedance
  • Zero noise
  • Infinite Common-mode rejection ratio (CMRR).
  • Infinite Power supply rejection ratio for both power supply rails.
